Bonding and sealing in caravan and mobile home construction

Weiss offers you highly durable adhesive systems for a wide variety of applications in caravan and mobile home construction, tailored to the specific requirements of this market segment. Ensure the required high quality of your products with our adhesives and achieve strengths that ensure a secure and permanent connection of your parts even under extreme loads.

Surface bonding

With the two 1-C-PUR adhesives COSMO® PU-160.530 and COSMO® PU-160.540 we have two adhesives in our range of ­products that can cover nearly all facets of surface bonding. 

COSMO® PU-160.540

1-C-PUR adhesive

If it shall be a specialist for the construction of side walls, e.g. on the basis of GRP/XPS/GRP, a fast COSMO® PU-160.540 with a skinning time of 9 minutes has established itself. The optimum full curing from +35°C provides for fast reaching of functional strength. With this, a controlled, lean and fast production is accomplished. These are important criterions for a cost-efficient manufacture of side wall elements.


  • Manufacture of sandwich and balustrade elements
  • Bonding of surfaces
  • Production of side walls of caravans 

Special properties

  • Fast skinning time
  • Tough-elastic adhesive joint
  • Good penetration properties in EPS
  • Solvent-free
  • Expands (foams) during the curing process
  • Good adhesive properties to GRP top coat and inner cores like XPS-, EPS- and PUR foams
  • Good weather-resistance
  • Compared to other 1-C-PUR adhesives of the COSMO® PU series, it faster cures fully at temperatures of >+35 °C
  • Faster process times possible

COSMO® PU-160.530

1-C-PUR adhesive

The COSMO® PU-160.530 is always used in industrial fields where a variety of substrates that are hard to bond, like PVC, ABS, PS, PC or also metals and mineral substrates with fluctuating qualities can occur. 

Briefly said: the safety backup for your bonding on site. 

Due to its very good adhesion to many materials and qualities, this adhesive ensures a maximum of safety and gives more space for your process control.


  • For universal use
  • Manufacture of sandwich and balustrade elements
  • Bonding of surfaces
  • Diverse industrial fields 

Special properties

  • Long processing time
  • Outstanding variety of application possibilities
  • Elastic adhesive joint
  • Solvent-free
  • Expands (foams) during the curing process
  • Goo adhesion properties with PVC, ABS, PS, PC, 
  • metals and mineral substrates
  • Good bonding strength at heat
  • Good weather-resistance
  • Can be over-coated with many paint systems

Assembly bonding

COSMO® HD-200.121 

The highly reactive  2-C-STP Assembly Adhesive

The fastest hardening scenarios with the accelerated 2-C-STP at full control of process can be generated with this adhesive. Combined with a very wide range of application possibilities and the lowest ageing behaviour under high climatic load, this is a top performer in our portfolio.


  • Assembly bonding
  • Sealing bonding
  • Highly weathered bonding 
  • outdoors
  • Bonding of difficult substrates
  • Leaf-enclosing entrance doors 


  • Controlled process times
  • Functional strength after 45 hours
  • Very good dosing behaviour
  • Very good weather-resistance
  • High temperature acceptance
